Lucas Oil 10873 Diesel Deep Clean - 64 Ounce (Pack of 6)

This stuff absolutely works! I'm running a Freightliner 2024 Cascadia with the dd15 Detroit engine. And if anybody who drives truck professional for a living nose these things plug up pretty quickly. I drop a bottle of this stuff in it at least once a month and I don't have any problems with it derating itself or any of the engine lights coming on because of the filter. A 64 oz bottle will treat 120 gallons so I dump it in one tank and even though it draws from both tanks it still gets the job done if I definitely want the job done I'll get two bottles and dump one in each tank it doesn't hurt if you over treat. If you're a truck driver or if you have your own personal diesel pickup and you want to keep that filter clean use this product trust me it absolutely positively works!
